Finite Element Stress Computations Applied to Images of Damaged Concrete: A Possible New Diagnostic Tool for Concrete Petrography

摘要

Concrete petrography is used to assess damaged concrete in order to determine the probable mechanism of damage. However, using traditional petrographic analyses, it is often difficult to say what mechanisms caused the crack damage, since many deterioration mechanisms produce cracks. This article describes a hybrid imaging-finite element modelling technique that can be used to help determine the mechanism of damage in such cases. This application is intended to assist concrete petrographers in the assessment of degradation mechanisms.
